Suitable forename for a saintly female? (6)

I believe the answer is:

stella

I'm a little stuck... Click here to teach me more about this clue!

'saintly female?' is the definition.
The definition suggests a singular noun which matches the answer.

'suitable forename for a' is the wordplay.
'suitable forename for' becomes 'stell' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'stell'+'a'='STELLA'

Can you help me to learn more?

(Other definitions for stella that I've seen before include "- Gibbons (Cold Comfort Farm)" , "lady?" , "Swift alias for Esther" , "Paul McCartney's daughter" , "woman" .)

I've seen this clue in the Evening Standard.
